AWTToolKit thread crashes in JNU_GetEnv

There're lots of recent reports in the Microsoft's winqual website (https://winqual.microsoft.com/) reporting about this crash.

I download 2 cab files, each of which contains a mini dmp file and both dmp files have similar thread stack when using windbg to analyze them.

Attached the 2 cab files and the output from windbg from my debug session on analyzing a dmp file.

The crash occurred with JRE 6u18 b07.
